Patent ES-367586-A1 (ES)
Title: Apparatus for imparting a predetermined value of twist to a material
IPC: D07B7/02
Filed: 1969-05-23
Abstract: Cable 4 is twisted before passing to a rotating take-up cradle and reel 7 by a twisting unit 12, two of which are shown in Fig. 1, each mounted for rotation about the cable axis and including a flexible endless rope 17 wound helically round the cable in frictional engagement therewith and a braked sheave 22 resisting movement of the rope. As the cable 4 is drawn towards the take-up cradle 7, the rope 17 exerts a twisting force thereon. To provide a substantially uniform twist along the cable 4, a photocell unit detects variations from the required lay by changes in position of a line printed on the cable by a wheel 49, the output from the photocell unit being used to control a magnetic clutch braking the sheave 22, and thus to control the twisting force. The rope 17 is stated to produce a substantially circular cross-sectional configuration of the cable 4. A spring-mounted sheave 24 takes up slack produced in the rope 17 by variations in the cross-section of cable 4. One, two or four twisting units 12 may be used, and each may carry more than one rope 17.

Title: Process and apparatus for the continuous tension-free fixing and shrinking of cables of uncrimped filaments
IPC: D06B17/02
Filed: 1969-08-19
Abstract: In a process for continuously fixing and shrinking tow of uncrimped filaments in the absence of tension, the yarn is injected by means of a compressible fluid from a rotating injector, whose yarn outlet opening is eccentric relative to its axis of rotation, into a treatment zone, the yarn being subjected to a fixing and shrinking treatment in the treatment zone and guided therefrom to a winding means. As shown the tow 3 is delivered to the injector 1 in the direction of arrow "A". The injector is supplied through pipe 2 with a compressible fluid, e.g. air, flowing in the direction of arrow "C". The injector 1 is rotated in known manner, for example, by a belt 5. The tow 3 and the air are delivered preferably obliquely downwards towards the inner wall of the tube 6 through the eccentrically positioned yarn-outlet opening 4. The air can escape through the openings in the direction of the arrows "D". The tow 3 is deposited helically in layers and moves under its own weight or the weight of following tow through the heating zone whose temperature is sufficient to effect fixing and shrinkage. The heating system 8 is supplied with a heating medium which flows in the direction of arrows "E", and "F". The lower end 611 of the tube forms an angle [alpha] with the upper end 61, termed the bending angle which is preferably greater than 90 degrees. The fixed set and shrunk cable accumulates in the bend 61 of the tube before being drawn off in the direction of the arrow "B".
